DISK- COIDT-ER MQUNTING.

To all whomz't mag concern 'Be it known that I, EDGAR B. W ns, a citizen of .the United States, residing at Mendota, in the county of Lasalle and State of Illinois, have invented certain new and useful Improvements in Disk-Colter Mountings, of which the following is a specifica- .tion.

The present invention relates to a 'pecul-. iar formation of the parts which constitute the bearing and mounting for a disk 'colter;

"lug 17 which, as more clearly illustnated used in conjunction with the ordinaryplow.

The objects of the present invention :are

.to arrange ,a mounting for the .colter which will enable a plurality of different adjustments to be given to the colter, whereby it may be properly positioned in accordance with the various conditions and kinds of soil being plowed and the various methods of plowing employed.

A further object of the invention is to utilize the same connecting medium which connects the bearing block of the disk to its mounting to secure a scraper standard to said bearing block; and a further object of the invention is to provide amounting which is simple and durable of construction containing rigid parts which will not beliable to become broken during ordinary usage.

The invention further consists in the .features of construction and combination .of parts hereinafter described and claimed.

In the drawings, Figure 1 is an edge view of .a disk colter supported by .the mounting of the present invention; Fig. 2, a side elevation of the parts-shown in Fig. 1; and Fig. 3, asection on line 3-- 3of Fig. 2, looking in the direction of the arrow.

Referring to the drawings, the invention is illustrated as applied to a disk colter 4; of any suitable construction, the mounting of the present invention being, as heretofore stated, particularly adapted for usage with colter plows.

The device is illustrated as comprising a spindle 5 which is secured by suitable fastening means 6 to the disk body and which has an axial bore 7 adapted to receive a bolt or stem 8 which is held in place by means of a threaded washer or cap 9. The spindle 5, as is usual in such constructions, is adapted to rotate with the disk 4. Said spindle is revolubly mounted within a stationary bearing block 10, and this block, as will be more clearly seen by referring to Fig.

2 of the drawings, is provided with two op- Specification of Letters Pa tent.

posed flat faces 11 .and :12, and said block is further provided with upper and lower bores adapted to receive bolts or other similar members 1 1. These bolts-extend through :a plate 15 which is zprovided with :a flattened face adapted :to rest :against'the face 11, and said plate, as is moreclearly shown in Fig. 1, is provided with upper and lower arcuateshaped slots '16 through which the bolts 14 pass. The plate 15 has integrally formed therewith or fined securely thereto a spliting or mounting therefor, the lower end of the #rod being locked in position through the medium of a removable locking member 20 entered through the outer end of the split lug 1-7.

The rod 1-9, as illustrated, is of crank formation, and is provided with an upper offset portion .21 which is suitably secured in place upon .a portion of the frame structure 22 by removable :locking means 23. By means of the connection above described, a strong and rigid mounting is provided for the disk 4 land the parts of :said mounting are so arranged as to permit of a variety of adjusting movements being allowed said disk. The firstof said adjustments is .provided, by reason of the slot 16, in the plate 15 in conjunction with the bolts 14 passing through the bearing blocks, this construction being referred to in the claims as a slot and bolt connection. By means of this connection, an angular adjustment of the disk can be obtained, the loosening of the nuts upon the ends of the bolts 1 1 permitting the bolts to move in said slots and said bearing block and disk to be swung about a :center extending at right angles to the axial center of the disk, thus permitting said disk to be moved into or out of a true vertical position and placed at any angular position desired.-

By means of the adjustable or removable locking connection 20, which holds the rod 19 in fixed position with respect to the plate 15 and bearing block 10, adjustment of the disk about the center of the rod 19 can be obtained, and also adjustment longitudinally of said rod. It will be obvibus that by loosening said fastening means, the plate 15, to-

.gether with the bearing block and disk, can

be swung around the rod 19 as a center into any desired position and can also be moved longitudinally upon said rod to raise or lower the disk as desired.

By making the rod 19 crank-shaped, an adjusting movement is obtained having the upper offset portion of said rod as the center of movement, it being obvious that by loosening the locking member 23 said rod can be swung around the oifset portion 21 as a center moving the plate 15, together with the bearing block and disk, into desired po sition. A limited adjustment of the same nature can, of course, be obtained by swinging the disk and block about the center of the lower portion of the rod 19, but, ob viously, a greater degree of adjustment can be obtained by utilizing a rod of crank formation than would be possible by using a perfectly straight rod.

The face 12 of the bearing block is preferably grooved to receive a scraper standard 24 and this standard is held in position by means of the bolts 14:, thus utilizing a single locking means for connecting the block to its mounting and for holding the scraper standard in position, said standard, as illus trated, has secured to its upper end a suitable scraper 25.

From the foregoing, it will be seen that an adjustment can be readily and quickly obtained to meet any condition of soil or plowing which may arise, and that these adjustments can all be made without disassembling the disk or bearing block from any of its parts.

In addition to the adjustments heretofore described, a further adjustment of the colter can be made in the following manner: By loosening the locking member 20 and the lockin member 23, the rod 19 can be swung around the center of the offset portion 21 and moved into desired position. The colter can be swung about the center of the lower part of the rod 19, so as to bring it in the same angle in which it was lying before the adjustment, but moved farther away or closer to the furrow being plowed, as desired.

I claim:

1. A mounting for a disk of the class described, comprising a bearing block, a spindle secured to the disk and rotatably mounted in said block, two opposed faces of said block being flattened, a plate resting against one flat face, a slot and bolt connection between said plate and block, whereby adjustment of said block and disk about a center extending at right angles to the axial center of said disk is provided, a scraper standard on the other flat face, said bolt connection serving also to secure the said scraper standard in position, a vertically extending rod, a bearing for one end of said rod secured to said plate, and releasable locking means for securing said rod in said bearing, whereby adjustment of said block and disk longitudinally of said rod is provided and also about said rod as a pivotal center, and means for securing the other end of said rod, substan tially as described.

2. In a mounting for a disk of the class described, the combination of a block provided with a vertically extending flat face, a spindle secured to the disk and rotatably mounted in said block, a plate resting against said flat face, a series of slot and bolt connections between said block and plate, said connections being located upon opposite sides of said spindle, said connections permitting adjustment of said disk about a center at right angle to the axial center of said disk, a vertically extending rod offset at its upper end, a mounting for the lower end of said rod secured to said plate, releasable locking means for securing said rod in said mounting whereby said block and disk may be adjusted using the lower end of the rod as the center, said adjustment being in the same plane as the axial center of said disk, said last named releasable locking means also permitting adjustment of said disk in a direction longitudinally of said rod and releasable locking means for securing the upper offset end of said rod whereby said disk may be adjusted using the upper end of the rod as a center of movement, substantially as described.
